The White House on Monday unveiled a $4.7 trillion government spending plan for 2020, a request that includes President Donald Trump's call for another $8.6 billion for his signature project, construction of a wall on the U.S.-Mexican border to thwart illegal immigration.

Trump's request for border wall funding presages a new fight with lawmakers over the issue in the coming months during the third year of the Trump presidency. Key opposition Democratic lawmakers immediately vowed to block wall funding.

The Trump budget plan calls for a five percent funding boost for the Pentagon and a five percent cut in nonmilitary spending, while reducing spending on popular programs providing health care for older Americans and the poor. Military spending would increase from $715 billion this year to $750 billion.

A senior Trump administration official said the plan calls for cutting "many, many programs that we consider wasteful."

Even so, the Trump administration is predicting a $1.1 trillion deficit in the budget year starting in October, comparing spending to revenues from taxes and fees the government collects.

Senate Democratic Leader Chuck Schumer called Trump's proposal "a disgraceful budget" and "a gut-punch to the middle class."

"It would dramatically widen the gap in income and wealth between our nation's richest citizens and the rest," Schumer said. "The budget slashes domestic programs, including investments in infrastructure, housing, education, and the environment."

Trump lost the first round in his battle with Congress over wall construction money, with lawmakers rejecting any appropriation for the wall, while offering nearly $1.4 billion in money for barriers. That led Trump to declare a national emergency to bypass Congress and tap funds already allocated for other projects to build the wall.

The Senate this week could join the House of Representatives in revoking Trump's emergency declaration although Congress appears to lack the two-thirds majorities needed to override Trump's expected veto of the vote against the wall. Numerous lawsuits are also challenging Trump's emergency declaration.

Trump's new request for wall funding comes just weeks after he ended a record 35-day partial government shutdown, a dispute that centered on his request for $5.7 billion for wall construction money. When lawmakers refused, he declared the national emergency.

Schumer and House Speaker Nancy Pelosi said in a joint statement Sunday they hoped the president had "learned his lesson" from the shutdown.

Trump "hurt millions of Americans and caused widespread chaos when he recklessly shut down the government to try to get his expensive and ineffective wall," their statement said. "Congress refused to fund his wall and he was forced to admit defeat and reopen the government. The same thing will repeat itself if he tries this again. We hope he learned his lesson."

But White House economic adviser Larry Kudlow said Sunday that Trump has justified his call for the wall's construction, even though polls show a majority of voters oppose it.

“I would just say that the whole issue of the wall, of border security, is of paramount importance,” Kudlow said. “We have a crisis down there. I think the president has made that case effectively. It’s a crisis of economics, it’s a crisis of crime and drugs, it’s a crisis of humanity.”

U.S. presidents and Congress have traditionally squabbled over budgets, which spell out how to spend taxpayer dollars and the size of annual deficits.

The current 2019 budget is more than $4.4 trillion, with a deficit of about $1 trillion expected, largely because of Trump's 2017 tax cuts.

There are signs the U.S. economy, which grew at a 2.9 percent pace last year, is slowing. (VOA)
